The Bernardo and Flott metal chop saws in this catalog range from €829 (CS 225, entry-level single-phase) to €5,111 (Flott KS 315 M, TCT blade without base). The Bernardo CS series — models from Ø 225 to Ø 350 mm — are equipped with HSS blades with integrated cooling lubrication: the standard system for cutting common steel, stainless steel, and solid materials cold in the workshop. The complete metalworking range also includes the semi-automatic CS 350 SA model with pneumatic head lowering for small production runs. Official Bernardo and Flott distributor since 2007.

Frequently Asked Questions

What is the difference between an abrasive chop saw and a metal-cutting band saw?

The disc cutting machine cuts in 15–30 seconds with an HSS or TCT blade: clean, vertical cut, suitable for pieces of defined length and sections up to Ø 100–150 mm. The band saw is slower but works on large sections, produces less heat, less noise, and less waste. For series cuts on medium profiles, the disc cutting machine is more productive; for large diameter bars or aluminum sheets, the band saw is more suitable.

What do HSS blade and TCT blade mean: which one to use for stainless steel and which for aluminum?

HSS (High Speed Steel) is high-speed steel: it cuts at low rotation speed with lubrication-cooling, suitable for construction steel, stainless steel, and ferrous materials. TCT (Tungsten Carbide Tipped) has tungsten carbide teeth, works at high speed without cooling, and is optimized for aluminum, brass, copper, and non-ferrous materials. Using HSS on aluminum is possible but wears out the coating; using TCT on stainless steel without cooling burns the teeth in a few cuts.

What is the maximum cutting capacity with a Ø 315 mm blade on tubes and solid materials?

The CS 350 SA (€4,599) has pneumatic head lowering with adjustable speed: the operator clamps the workpiece, starts the cycle, and the machine completes the cut autonomously. It is suitable for 15-20 identical pieces per day or more, where the time saved compared to manual lowering accumulates. For single pieces or intermittent work, a manual model CS 315 H or CS 350 L is sufficient and costs approximately €1,700 less.

When is the CS 350 SA semi-automatic chop saw more suitable than a manual model?

The CS 350 SA (€4,599) has pneumatic head lowering with adjustable speed: the operator clamps the workpiece, starts the cycle, and the machine completes the cut autonomously. It is suitable for 15-20 identical pieces per day or more, where the time saved compared to manual lowering accumulates. For single pieces or intermittent work, a manual model CS 315 H or CS 350 L is sufficient and costs approximately €1,700 less.

The Flott KS 315 M comes without a base: how is it installed and what is its purpose?

The Flott KS 315 M is a saw head designed to be mounted on an existing heavy-duty workbench or a customer-welded structure. Delivery without a standard base makes sense for those integrating the machine into a cutting line with roller conveyors and automatic stops, where a traditional base would be an obstruction. It requires a rigid support surface weighing at least 150 kg with holes for M12 bolt fixation.

Can the metal chop saw cut aluminum and non-ferrous materials?

Yes, with the right blade. The Bernardo CS models with HSS blades cut aluminum acceptably but produce burrs. For continuous production of aluminum, a TCT (tungsten carbide tipped) blade is needed, like the one fitted on the Flott KS 315 M. The blade rotation speed should be set to the high range (36 rpm on the CS 315 L/H) and it is recommended to reduce or eliminate coolant, which causes chip buildup on the disc when cutting aluminum.

HSS blade or TCT blade: how cutting changes

The HSS (high-speed steel) blade cuts at low rotational speed — 18 or 36 rpm on Bernardo CS models — with continuous white water cooling that keeps the cutting edge below 60°C. This makes it suitable for structural steel, stainless steel, structural tubes, and solid materials up to Ø 80–100 mm. The TCT (tungsten carbide tipped) blade of the Flott KS 315 M, on the other hand, works at much higher speeds, without cooling, and is optimized for aluminum, brass, light profiles, and non-ferrous metals where heat is not the problem but cut quality is. Using an HSS blade on aluminum produces an acceptable cut but wears out the coating: for continuous production on non-ferrous metals, TCT is the correct choice. For replacement HSS and TCT blades in diameters Ø 225–350 mm: metal sawing machine accessories and spare parts.

Bernardo CS series: from Ø 225 mm to semi-automatic

The CS 225 and CS 250 eco models cover workshops with cutting needs on small sections, single-phase power supply, and a limited budget. From the CS 275 H upwards, you enter the professional range with a self-centering double vice, included base, and oil-bath hardened gear transmission: the construction that withstands 8-hour shifts without mechanical play. The CS 315 L (€2,732) cuts tubes up to Ø 100 mm and solid materials up to Ø 55 mm; the CS 315 H (€2,903) features a 4-jaw vice with an opening up to 150 mm and head rotation of 90° both to the right and left. The CS 350 SA (€4,599) adds pneumatic head lowering at adjustable speed: the operator clamps the workpiece, starts the cycle, and the machine completes the cut autonomously — a concrete advantage when cutting 20–30 identical pieces per day. Those who combine cutting with turning operations can find the metal lathe range in the dedicated section.

Flott KS 315 M: without base, bench-mounted or on custom structure

The Flott KS 315 M (€5,111) is delivered without a base: it is a saw head to be installed on an existing heavy-duty workbench or on a structure welded by the customer. This choice makes sense for those who integrate the machine into a cutting line with roller conveyors or automatic stops, where a standard base would be an obstacle. The Ø 315 mm TCT blade works on aluminum, brass, copper, and non-ferrous metals with clean cuts and no burrs to be deburred. For those looking for a turnkey machine with a pre-assembled base and cooling lubricant system, the Bernardo CS models are the direct route. The metal band saw, on the other hand, covers cuts on large sections over Ø 100 mm or on long bars where the disc cutting machine cannot reach.
